One issues atm:
My polyfill only works for 2D transformations, 3D with perspective do not work (yet). Have to figure out how to do this. Cause of that, also my spec only works for 2D. I've found some spect for the 3D matrix, wich then also could maybe reused: https://drafts.csswg.org/css-transforms-2/#accumulated-3d-transformation-matrix-computation
